Distribution of Palindromes in Base b

A number is palindromic if its reversed digits give the original number. For example, 1123211 is a palindrome. This Demonstration shows the distribution of palindromic numbers when written in base (up to 16) for all products , when and are both less than 100. You can see the values as tooltips. Being a palindrome in one base does not mean that a number is necessarily a palindrome in another base.
